Ms. Ellen Barnes is a Senior Technical Specialist in Reliability
and Statistics at Ford Motor Co., where she has worked on both design and
manufacturing issues. Ellen discussed
statistical work she has done on testing the requirement for independence,
specifically with Chi-Squared probability plots. Her motivation was
based on work she does with warranty data, which is often correlated.
Her research has been with Survival Trees (binary recursive partitioning).
She is looking to develop an analog of half-normal plots that could be
used to test nodes and partitions.
